Jayant is Professor of Surgery and Oncology at University College London and a Consultant Surgeon specialising in the diagnosis and treatment of diseases of the breast. He was instrumental in developing a revolutionary treatment which has successfully treated 20,000 breast cancer patients across the globe.
He has focused his research over the past twenty years on improving the treatment of breast cancer, authoring over 300 scientific publications, including journal articles, books, and conference papers.
In the early 2000s Jayant, together with Professor Michael Baum and Professor Jeffrey Tobias, developed the technique called targeted intra-operative radiotherapy (TARGIT) to treat breast cancer, delivering single-dose radiotherapy from inside the body via a small ball-shaped device, placed inside the breast immediately after removal of the tumour. The treatment takes 20-30 minutes, compared with conventional radio therapy taking 3-6 weeks of daily treatments.
He has been invited to give over 150 talks, mainly on breast cancer in scientific conferences, including at the British Association of Surgical Oncologists, European Breast Cancer Conference (EBCC), European Cancer Conference (ECCO) and the American Society of Breast Surgeons.
He is regularly called upon for his expert knowledge by the BBC and has been featured in Time magazine and Reader’s Digest.
